Description

  The present invention relates to a claw-shaped fixing member, and particularly to a claw-shaped fixing member that is inserted and fixed in a slit provided in a pipe steel material or a channel steel material.

  Usually, as a dowel for supporting a shelf board or the like, a screw hole or a round hole is provided in a column, and the dowel is screwed or inserted into the hole and fixed. In the dowel having such a configuration, it cannot be attached to a support member such as a pipe steel material or a channel steel material provided with a slit.

  The applicant has developed and sold a claw-like fixing member that can be attached to a support member made of such pipe steel or channel steel (see Non-Patent Document 1). This claw-shaped fixing member is inserted and fixed in a predetermined slit of a support member provided with a plurality of slits, and supports the shelf board and the like using these claw-shaped fixing members.

  This claw-shaped fixing member will be described with reference to FIGS. FIG. 17 is a side view showing the attachment main body of the claw-shaped fixing member, FIG. 18 is a front view of the same, and FIG. 19 is a perspective view showing the claw-shaped fixing member showing a state in which a cylindrical dowel is attached to the attachment main body. 20 is a perspective view showing an example of a support member made of channel steel, FIG. 21 is a side view with a part broken away showing a claw-like fixing member showing a state in which a cylindrical dowel is attached to the attachment main body, FIG. FIG. 23 is a partially cutaway side view showing a state in which the claw-shaped fixing member is attached to the slit of the support member.

  As shown in these drawings, the attachment main body portion 100 is formed by punching a plate-shaped steel material into a substantially L shape, and is provided with a claw portion 102 connected to the horizontal portion 101 and inserted into the slit. The claw portion 102 is provided with an upper engagement portion 102a on the upper side of the horizontal portion 101 and a lower engagement portion 102b on the lower side. The length of the claw portion 102 in the vertical direction is longer than the length of the slit to be attached. Moreover, the width | variety, ie, thickness, of the nail | claw part 102 is formed smaller than the slit width so that it can insert in a slit. A male screw part 104 is provided on the part of the horizontal part 101 opposite to the claw part 102.

  A cylindrical dowel 200 is attached to the attachment main body 100. The cylindrical dowel 200 is provided with a female screw 201 that is screwed with the male screw portion 104 provided in the horizontal portion 101 described above.

  A cylindrical dowel 200 is screwed into the opposite side of the claw portion 102 of the attachment main body 100 formed in this way, so that a claw-shaped fixing member as shown in FIGS. 19 and 21 is formed. This claw-shaped fixing member is inserted into a slit of a support member made of pipe steel or channel steel having a slit and attached.

  As shown in FIG. 20, a plurality of slits 301 are provided at equal intervals on the surface portion of the support member 300 made of channel steel. Further, a hole 302 is provided on the surface of the support member 300, and a screw is passed through the hole 302 so that the support member 300 is fixed to a wall surface or the like.

  A method of attaching the claw-shaped fixing member to the predetermined slit 301 of the support member 300 will be described with reference to FIGS.

As shown in FIG. 22, the claw-shaped fixing member is inserted into the slit 301 from the oblique direction with the upper engaging portion 102a of the claw portion 102 facing upward. And as shown in FIG. 23, the nail | claw part 102 is rotated in the slit 301, and it sets so that the nail | claw part 102 may become parallel to the inner wall face of steel materials in the slit 301. FIG. The horizontal portion 101 on the lower engagement portion 102b abuts the lower portion 301a of the slit 301 with the weight of the claw-shaped fixing member, and the upper engagement portion 102a of the claw portion 102 contacts the inner wall surface 302 of the slit 301. And the lower engaging portion 102 b come into contact with each other, and the claw-shaped fixing member is attached to the slit 301. Even in this state, the claw-shaped fixing member is attached and fixed to the slit 301, but in this example, the cylindrical dowel 200 is screwed to increase the strength of the claw-shaped fixing member. That is, when the cylindrical dowel 200 is screwed and the end surface of the cylindrical dowel 200 is brought into contact with the surface of the support member 300, the support member 300 is sandwiched between the claw portion 102 and the cylindrical dowel 200, and the nail-shaped fixing member is It becomes possible to attach to the slit 301 firmly.
